ELECTRICAL DEHYDBA'I0R.

.application led December 19, 1921.

To all whom.. it may concern.' Be it known that l, lli/'ILLIAM 0. EDDY, a citizen of the United States, residing. at Los Angeles, in the countyl of Los Angeles and State of California; have invented a new and useful improvement in Electrical Dehydrators, of which the following is a specification..

My invention relates to dehydrators which are adapted to remove the Water from petroleum emulsions. ltv is a well known fact that it' such. emulsions are passed through an electric field of sufficiently high intensity that the fine water particles in that field are agglomerated into larger masses vwhich will readily separate therefrom by gravity. There have been developed various types ot electric dehydrators for accomplishing this result.

The principal object of my invention is to produce such a dehydrator in which the capacity willfbe large and in which there will be great certainty of operation.

Further objects and advantages will be nialle evident hereinafter.

eferring to the drawing which is Jr'or illustrative purposes only:

Fig. 1 is a vertical section through a preferred embodiment of my invention, and,

Figf is a section on a plane represented by the line 2-2 of Fig. l.

In the form of the invention shown a shell 1l is providedv having an enlarged top 12 and having an inlet pipe i3 through which the emulsion to be treated is passed..l A pipe 14 is provided for withdrawing the treated oil and the separated water from the bottom. of the tank. Supported on insulators 20 in the top of the tank is a spider 21. Turning freely in the spider is a shaft 22,l this shalt bein turned by means of a belt, not shown, wfhic passes around a pulley 23 or by any other convenient practical means. Suspended on thevbottom of the Shaft 23 are -four rods 30 which pass through annular members 31, and are secured thereto by any convenient means such, for example, as by welding. Secured to the inside ot the tank 11 are three angle iron rings 33 having a circular opening therein concentric with. the outer surface of the rings 31. rThe spaces between the rings 31 andthe rings 33 form an outer electric field.

Supported on a column l0 vin a standard il secured in the bottom ot the shell is a seone terminus of an inner Serial No. 523,36.

ries of discs 42 which are cylindrical in contour and which are concentric withv the inner edge of the rings 31.

A transformer 5() 1s provided, this transformer having a low tension primary 51 and a high tension secondary 52. rIhe secondary is connected through a wire d3 With the spider Q1 and through a wire 54C with the tank l1. An electro-motiveforce is thus impressed across the outer field between the members 3l and 33 and across thevinne'r-eld between the members The emulsion passes through these lfields and the water particlesthei'ein are agglomerated in that passage.

l claim as `my invention.:

l. A dehydrator for petroleum emulsions coinprising'a tank having a circular inner surface forming one terminus of an outer electric field; a stationary structure in said tank having a circular outer surface forming electric field; an electrically conducting member having a circular outer surface forming the inner terminus for said outer electric field and a circular inner surface forming the outer terminus for said innervelectric field; means for electrically connecting said stationary structure to said tank; andmeans for impressing an electromotive force between said tank with its stationary structure and said electrically conducting member.

2. A dehydrator for petroleum emulsions comprising a tank having a circular inner surface forming one terminus of an outer electric field; a stationary structure in said tank having a circular outer surface forming one terminus of an inner electric field; an electrically conducting member having a circular outer surface forming the inner terminus for said outer electric field and a circular inner surface `forming the outer terminus for said inner electric field: means for rotating said member about; the center of its circular outer surface; means for electricall. connecting said stationary structure to sai for impressing an electromotive force between said tank with its stationary structure and said electrically conducting memr. v 3. A dehydrator for petroleum emulsions comprisingV a tank having a circular inner 31 and the member 42.

tank; and means l The spaces between the d1scs 4:2 and the rings 3l. form an inner .electric field. f

structure surface forming one terminus electric field; a stationary structure in said tank having a'circular outer surface vforming one terminus of an inner electric field; an electrically conducting member having a circularV outery surface forming the inner terminus for said outer electric field and a circular inner surface forming the outer terminus for said inner electric lield; means for electrically connecting said stationary structure to said tank; a pipe for introducing emulsion into'said tank; a pipe for withdrawing cleaned oil from said tank, said pipes being so placed that oil passing from one to the other must pass through either said outer or' said inner field;y and means for impressing an' electromotive 'force 4between said tank with its'stationary 4 and said electrically conducting member. n

4. A dehydrator for petroleum emulsions comprising a tank having a circular inner surface ,forming one terminus of an outer electric field; a stationary structure in said of an outerl lterminus for said outer -or said inner field;

ing one terminus of an inner electric field;

.an electrically conducting member having a circular outer surface forming the inner electric field and a circular inner surface forming the outer terminus for said inner electric field; means for rotating said member about the center of its circular outer surface; means for electrically connecting to said tank; a' pipe for introducing emulsion into said tank; a pipe for withdrawing cleaned oil from said tank, said pipes being so placed that oil.passing from one to the other must pass'through either said outer and means .for impressing an electromotive force between said tankwith its stationary structure and said electrically 'conducting member.

In testimony whereof, i have hereunto set my hand at Los Angeles, 13th day'of Becember, 1921.
